yeah I think that would be fine, thats about the size of the one I have but I brought a divider from the LFS and split it into 2 sections so straight after spawning I could put the breeding pair into the other half without having to bag and reclimatise them into the main tank. The key I am told is to use a single sponge filter rather than a standard internal filter as the wee fry get sucked into a normal filter.
